Liquid sampling device



June 1935- M. .1. CARPINELLO LIQUID SAMPLING DEVICE Filed April 25, 1953 ATTORNEY Patented June 11, 1935 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a liquid sampling device and is adapted to take samples of liquids at different depths simultaneously.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not aifect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. 1 is a front elevation of the device with the closure partly open and the device being shown in a liquid of which samples are to be taken by means of the device.

Fig. 2 is a fragmentary front elevation of the upper portion of the device.

Fig. 3 is a broken section of the device taken on line 3-3 of Fig. 2; and

Fig. 4 is a section taken on line 4-4 of Fig. 2.

Referring to the drawing for a more detailed description thereof, the numeral 5 indicates an elongated rod like container of substantially semicircular cross sectional configuration and having a bottom 5a and a top 5b. Horizontal partitions 6 divide the container into a plurality of adjacent superimposed compartments. The container 5 is provided with a relatively narrow opening in its front wall and extending centrally and longitudinally thereof and co-extensive therewith. The opening is adapted to be closed by a door or closure 7 which forms liquid-tight joints with the confronting portions 5d of the front of the container. The door I has reduced side portions which lie between the front of the partitions 6 and the mentioned confronting portions 5d of the container and are of less thickness than the middle portion of the door, the latter portion being flush with the front of the container. On one of the front portions 51) a scale is impressed and is for the purpose of indicating the depths at which the different samples of liquid are taken. A strap 8 spans the space between the upper ends of the front portions 5d of the container and is adapted to prevent the door from becoming separated from the container, a projection 9 being provided on the lower portion of the door. When the door is raised the projection 9 comes into contact with the strap 8 and the door is thus prevented from becoming separated from the container. The upper end of the door is provided with an aperture l so that a cord ll may be tied to the door for the purpose of raising and lowering it. A ring I2 is attached to the top of the container for the purpose of raising and lowering the same by means of a cord I3 attached to the ring.

In order to take samples of a body of liquid l in a, container, illustrated by the numeral I 6, the device of my invention is immersed vertically in the container, the device being heavy enough to remain in the vertical position. The door 1 is closed when the device is let down into the liquid. With the device in position for taking samples, the door is raised and the immersed compartments are filled with liquid. The door is then closed and the device is raised by pulling up on the cord I3. The device may then be taken to a laboratory, and after being placed in a horizontal position, face up, the door may be opened and liquid withdrawn from the various compartments and tested in any desired manner. The scale on the face of the container indicates the depth at which various samples were taken.

What is claimed is: I

1. A liquid sampling device comprising an elongated rod like container of substantially semicircular cross sectional configuration and having a relatively narrow opening in its front Wall extending centrally and longitudinally thereof, partitions in said container and providing superimposed compartments, a slidably mounted door for closing the opening, said door having reduced side portions extending to the sides of the container to close the compartments from each other and acting with the sides of the front wall to guide the door in its movement, a strip bridging the opening at its upper end, a projection on the lower end of said door to contact the strip to limit the upward movement of the door, said door being longer than the container to extend above the latter with an opening in the extension, flexible means secured in the extension opening to raise the door, a ring secured to the top of the container, and flexible means secured to the ring to raise and lower the container within a body of liquid.

2. A liquid sampling device comprising an elongated rod-like container having a relatively narrow opening in its front wall extending centrally and longitudinally thereof; partitions in said container providing superimposed compartments; a slidably mounted door for closing the opening, said door having reduced side portions extending to the sides of the container to close the compartments from each other and acting with the sides of the front wall to guide the door in its movement; a strip, bridging the opening at its upper end, and a projection on the lower end of said door to contact movement of the door.
